Cell Area-Based Method for Analyzing the Coverage Capacity of Satellite Constellations

Constellation-to-ground coverage analysis is an important problem in practical satellite applications. The classical net point method one of the most commonly used algorithms resolving this problem, indicating that computation efficiency significantly depends on high-precision requirement. On basis, improved cell area-based proposed paper, which a as basic analytical unit. By calculating accuracy area partly contained by ground region or covered constellation, accurate can be obtained accordingly. Experiments simulating different types problems are conducted, and results reveal correctness high method.
